A 21-year-old Hermitage woman who had been out drinking late one night in December gave her car keys to her 23-year-old boyfriend, thinking he was sober enough to drive.

But the night turned tragic when her boyfriend struck and killed two young men about their same age on Demonbreun Street near the Music Row roundabout, then drove her Toyota Scion across a median and hit a taxicab head-on.

Erin Brown's boyfriend was charged with vehicular homicide and assault. She had been in the passenger seat. But in a rare use of the law, prosecutors also are charging Brown with the same crimes.
